Diane Keaton has had relationships with a slew of high-profile men, including Warren Beatty, Woody Allen and Al Pacino. And she tells the upcoming Oct. 9 issue of Ladies’ Home Journal why these romances failed. “Managerial skills are necessary to handle men like that,” she says, adding, “I also don’t think I have a lot of nurturing skills. I needed as much as they needed, and that’s not a good mix.” Keaton reveals when she first saw Beatty, she thought, “He was very sexy, but a different kind of sexy. I mean, we’re talking pretty. Like Justin Bieber pretty.” She admits of Pacino, “I had a crush on him for 20 years,” and states, “I still love Woody.” As for Jack Nicholson, with whom she starred in 2003’s “Something’s Gotta Give” but never officially dated, Keaton says, “He’s very adept at being the person you want to watch, and I think it’s exhausting.” For now, Keaton is single.
